Far from backing up that assertion, your article only contradicts it. You cite polls showing that, over the last 20 years, the portion of the public in favor of outlawing interracial marriage has sharply declined. You also note that anti-miscegenation laws, nullified by the Supreme Court, were subsequently taken off the books by Southern states. And interracial marriages have increased fourfold. Surely, that reflects something of public attitudes, not universal, of course, but in a growing segment.

That is not to say all is well with attitudes toward intermarriage. There can be no question that interracial couples face massive problems. However, the assertion that the two worlds are increasingly alienated, without evidence, but rather in defiance of the facts, seems to be a case of nagging the public, doubtless well-intentioned, but counterproductive, tending to further alienation.

It seems odd to report a trend as if it were dictated, rather than denied by the facts. ROBERT TILOVE Roosevelt, L.I., Dec. 3, 1991
